FLANGE WRE NCH.

SPECIFICATION forming part of Letters Patent No. 411,80i, dated October 1, 1889.

7 Application filed August 23, 1888. Serial No. 283,586. (No model.)

To all whom it may concern.-

Be it known that I, JAMES F. GUTHRIE, .Ir., of Somerville, in the county of Middlesex and State of Massachusetts, have invented a new and useful Flan ge-WVrench, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 is an elevation showing my wrench applied to a flanged pipe. Fig. 2 is a plan, and Fig. 3 an end view, of what is shown in Fig. 1. Fig. A is a sectional view on line 4: a of Fig. 2. Fig. 5 is an' elevation showing a modified form of my wrench applied to a flange-pipe. Fig. (3 is a plan, and Fig. 7 an end view, of what is shown in Fig. 5; and Fig. 8 is a sectional view on line 8 S of Fig. 5.

My invention is a flange-wrench.

In the drawings, which show my invention embodied inthe best way now known to me, rocking j aw Ais mounted in carrier B,in which is mounted a threaded jaw-carrier A, provided, preferably, with a compound jaw A which is best made up of two members a, as shown. Carrier B is preferably formed with .a lip b to engage the flange when the wrench is used, and is provided with a thumb-nutb, through which jaw-carrier A passes, and by means of which it is moved, as will be plain without further description.

In the preferred form of my wrench, Figs.

1 to at, inclusive, jaw A is loosely pinned to carrier A, its members a being connected by folding links a, and provided with sidewise projections a at their outer ends.

When the wrench is used, carrier A is moved to carry jaw A a sufficient distance from the inner end of jaw A to admit flange D, and is then moved to cause the jaws AA to grip the flange.

with a handle a is then rocked on its ful crum a and the flange D readily turned, as will be plain without further description.

J aw A, which is provided- In order to readily tighten and loosen jaws A A I form nut?) with holes 17 in its periphery to receive a spike or the like, by means of which the nut is readily turned even when great force has been applied to the wrench and the members have become set. This is also a feature of my invention.

In Fig. 5 I showa modified form of jaw A the jaw being in this case of one piece and integral with the carrier A. Details of this modification are shown in Figs. 6, 7, and 8, and the operation of the modified form will be fully understood without further description, all the parts, except the jaw A being the same as in the preferred form.

I am aware of Roses patent, No. 383,544, dated May 29, 1888, and disclaim all that is shown in it.

What I claim is- 1. The herein-described combination of jaw A, carrier B, jaw-carrier A, and jaw A jaw A being fulcrumed in carrier B, and jaw-carrier A being mounted in carrier B, and jaw A being provided with one or more sidewise projections a all arranged to gripa flange between the inner end of the jaw A and the sidewise projections a all substantially as and for the purpose set forth.

2. Theherein-describedcombination of jaw A, carrier B, jaw-carrier A, jaw A and nut 11, jaw A being fulcrumed in the carrier B, in which is mounted jaw-carrier A and nut 12, the jaw-carrier A passing through the nut Z), and the jaw A being provided with one or more sidewise projections a all arranged to grip a flange between the inner end of the jaw A and the sidewise projections a all substantially as and for the purpose set forth.
